Improvement in umbrellas



UNITED STATES PATENT OFFICE.

WILLIAM DAMEREL, OF BROOKLYN, NEV YORK.

IMPROVEMENT IN UMBRELLAS.

Specification forming part of Letters Patent No. 49,986, dated September 19, 1865.

To all whom 'it 'may concern:

Be it known that I, WILLIAM DAMEREL, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Umbrellas and Parasols 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot' this specification, in which- Figure l is an axial section of an umbrellastick to which my improvement has been applied, the line ot' section being seen at w in Fig. 2. Fig. 2 is a detailed view of the crownpiece, to which the upper ends of the ribs are hinged, together with the colla-r, which in this example ot' my invention is placed within it'. Fig. 3 is a top view ofthe cap which covers or contines the cover of the umbrella.

Similar letters ot` reference indicate like parts.

The object of this invention is to make and connect the stick ot' an umbrella or parasol to the ribs and their co-operative parts in such a way thatv the said parts shall oe free to rotate on the stick, instead of being fixed thereto, so that when the umbrella is extended and in use, the part composing the cover will yield when it meets an opposing object, and will take a rotary motion on the stick, thereby relieving the hand and also the umbrella from strain.

In the example ot my invention here given A designates the stick ot' an umbrella, and D is the usual crown-piece, to the han ge of which the ends of the ribs are hinged. The crownpiece is held up to its place by means of pins E, which project from two or more points of the stick, thereby preventing it from falling down on the stick, but not opposing any resistance toits free rotation thereon. A collar may be used for this purpose instead of pins. The letters Gr G designate a thimble or t'errule, composed in this example of two equal parts, divided in the line'ot' the plane x, Fig. 2. The lower ends of the parts G G meet so as to present a smooth joint, making a smooth cylindrical surface, over which the crown-pieceD passes, as shown in Fig. l. The upper ends of the parts Gr Gr of the errule have projecting lips a a on theirv edges, which, when they come together,

form radial tlan ges, whose lower ends may it in notches cut on the upper edge of the crownpiece, if itis desired to connect them with said crown-piece. It is not necessary to connect them in this manner, and it' it is desired that they move always together they may be so fitted to each other as to produce friction enough to prevent them from rotating independently of each other.

U designates the usual cloth or other covering of the umbrella or parasol, which is conned between the crown-piece and a metallic cap, F, whose sides rise after the manner ot a cone; or the cap may be ot' a semicircular form, its crown being perforated to allow it to pass over the stick. The upper edges ot the cap are notched to receive the flanges a a, which serve to lock the cap to the ferrule. The crownpiece and cap are held down on the pins E by means of a metallic collar, B, or equivalent device,thereby, in conjunction with them, preventing those parts from having any longitudinal motion on the stick. One result of this construction is, that the frame of the umbrella or parasol--that is, the ribs and their covering and the crown-piece to which the ribs are hin ged-are permitted to revolve l'reel y npon the stick, so that when the ribs are extended, as when the umbrella is in use, if their ends or the edge of the cover come in contact with or receive a blow from any object, the frame will yield and will begin to revolve, thereby avoiding and preventing injury from tearing the cloth or breaking the ribs or other parts of the article.

Instead of using a metallic cap, F, to con^ ne the top ofthe covering to the crown-piece, I can use a ring or collar ot' elastic and flexible material-such, t'or instance, as rubber and its equivalents, and which is applied or slipped over and upon the collar B, or upon the upper part ot' the stick, its lower end compressing and confining the covering O to the crownpiece. Such tlexible collar should clasp those parts tightly, so as not to be liable easily to become displaced. Its operation will be to allow the crown-piece and ribs and covering of the umbrella to revolve on the stick without exposing the edges ot' the covering to the Weather. The cap F may also be tlxed to the collar B, and its lower edge be made flexible and be extended down over the crown-piece, so as to inclose the upper edge of the crowning C.

I claim as new and desire to secure by Letters Patent- 1. In umbrellas -and parasols, so securing on the stick the crown-piece or other device to which the upper ends of the ribs of such articles are attached as that the said crown-piece and the parts attached to it shall be capable of rotating on the stick7 substantially as described.

2. In combination, the crown-piece I), the collar Gr G, with the longitudinal lian ges a a, and a cap, F, for inclosing the upper1 edge of the covering G and confining it to the crownpiece, substantially as described.
